A device for preventing wind, sand, snow and dust

Abstract

The invention provides a device for preventing wind, sand, snow and dust, and the method is used for solving the problem that in the prior art, along with the increase in blocked sand soil quantity or blocked snow quantity and the like, the sand-resisting, windproof, dustproof or snow-resisting effect of a protecting net is obviously reduced, and therefore sand prevention, wind prevention, dust prevent or snow prevention cannot be carried out finally. The device for preventing wind, sand, snow and dust comprises a screen plate and a screen plate rack body, wherein two ends of the screen plate rack body are respectively provided with a first mounting hole and a second mounting hole, a first upright column is connected with one end of the screen plate rack body and provided with N first gear holes; a second upright column is connected with the other end of the screen plate rack body; one end of the screen plate rack body passes through the first mounting hole and the first gear hole by virtue of a first fixing piece and is fixed together with the first upright column; and the other end of the screen plate rack body passes through the mounting hole and the second gear hole by virtue of a first fixing piece and is fixed together with the second upright column. The device for preventing wind, sand, snow and dust has the advantage that the height of the screen plate can be increased so as to better perform protection.

Description

technical field [0001] The invention relates to a protection device, in particular to a device for preventing wind, sand, snow and dust applied to roads or railways. Background technique [0002] In order to prevent roads and railways from wind, sand, snow and / or dust, etc., the existing practice is to set up protective nets on both sides of roads or railways, but after long-term use, with the amount of blocked sand or snow, etc. The blocked sand, soil, live snow, etc. will cover the protective net from bottom to top, so that the sand-blocking, wind-proof, dust-proof or snow-blocking effect of the protective net will be significantly reduced, so that it will not be able to block sand, wind, dust or snow in the end. Snow. In addition, this method uses prefabricated concrete as columns, the protective layer adopts prefabricated concrete solid slabs, and prefabricated concrete blocks are used to connect with the concrete foundation. The structure is difficult to construct and ...

Problems solved by technology

[0003] The present invention proposes a device for preventing wind, sand, snow and dust, which solves the problem that in the prior art, with the increase of the amount of blocked sand or snow, the effects of sand blocking, windproof, dustproof or snow blocking of the protective net decrease significantly. As a result, it is impossible to prevent sand, wind, dust or snow in the end.
